Add the Events stuff back in

I removed the sample Events in modules that @benhowdle89 had added when we moved over to RequireJS.

I like the way Ben does it as per his blog: http://benhowdle.im/2012/12/03/using-jquery-custom-events-in-your-object-literal-and-observer-pattern-applications/

And I think we should show an example of this.

Thoughts?
